Sinara 8451 Thermostat
The Sinara 8451 Thermostat is a precision 2-channel temperature controller based on the Maxim MAX1968 driver, capable of driving 8.6W into a TEC or resistive heater. The sensor interface is based on 24-bit AD7172 ADC.
Temperature stability better than 1mK can be achieved; typically the temperature drift is around 300µK peak-to-peak over 10 hours.
Specifications:
- Channel count: 2
- Sensor: 10k NTC thermistor
- Load (heater/TEC) drive: up to 8.6W (+-2A with 4.3V compliance)
- Form factor: 3U module or stand-alone aluminum enclosure.
- Output connectors: Sensor and load connect via either terminal block connector on the front panel or via internal 100mil pin-header.
- Programming interface: Ethernet accessible via RJ45 connector on the front panel
- Power supply: +12V DC (1.5A max) supplied either by a front-panel barrel connector, via 100mils Zotino connector, or PoE (up to 30W).
- STM32 MCU
- Firmware
- With the included Control Panel, the Thermostat can be easily configured, and key parameters plotted in an integrated GUI.
